Converts WebP files to PNG format — modern websites to graphics with sharp edges, text overlays, screenshots, and images requiring transparent backgrounds. All conversion happens locally in your browser with no file size limits.
Converts GIF files to WebP format — simple animations, memes, and images on platforms that support animated GIFs natively to modern websites. All conversion happens locally in your browser with no file size limits.
Request PNG to HEIC output for Apple storage — but browsers have no HEIC encoder, so Canvas conversion fails locally instead of downloading. For Apple sharing convert PNG to JPG instead — local, unlimited saves.
Converts HEIC files to PDF format — Apple device photos to document sharing, printing, and archival with consistent formatting. All conversion happens locally in your browser with no file size limits.
Converts MKV files to MOV format — advanced video archiving with multiple subtitle tracks, chapters, and audio streams in one file to Apple ecosystem. All conversion happens locally in your browser with no file size limits.
HEIC (High Efficiency Image Container) uses lossy or lossless encoding and is best for Apple device photos — iPhone and Mac default format with excellent compression efficiency. PNG (Portable Network Graphics) uses lossless encoding and excels at graphics with sharp edges, text overlays, screenshots, and images requiring transparent backgrounds. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.

Seconds for typical files on a modern device; large files scale with size and CPU. Conversion speed depends on the machine, not the formats — close heavy tabs for big batches.
From lossy or lossless to lossless: quality is preserved as far as the formats allow.
Yes — archive HEIC originals before batch-converting. Re-converting from PNG back to HEIC never restores discarded data.

Bulk Image Format Converter
Convert image batches between JPG, PNG, WebP, and AVIF outputs (JPEG/PNG/WebP/AVIF/HEIC/HEIF/GIF/BMP/ICO/SVG inputs; HEIC via heic2any, SVG rasterized at intrinsic size or 1024px fallback) with a quality slider (10–100, default 80). Pair pages (?from/?to) preset the output. Flat ZIP renamed per file — local, 5-file guest batches, 25 signed-in, 500 Pro.
Image Format Converter
Convert one browser-decodable image to PNG, JPG, or WebP — the only outputs canvas can encode. HEIC/SVG/JXL/TIFF and other exotic targets fail honestly instead of pretending. Nothing is uploaded; every conversion runs in your browser.
